And here's my last question. The motor is out of a 91 C1500, but its a Goodwrench replacement crate. When selecting headers, do I need to buy ones specifically for the trucks or can I buy ones for the fullsize cars? Or, in other words, do the trucks and cars use the same header port?

ALL SMALL BLOCK CHEVY'S HAVE THE SAME EXHAUST PORT SPACING 1955+ including LT1. You need to pick headers that fit the cars frame. So buy a set for the wagon, doesn't matter what the engine came out of as long as it's a SBC.

So I have the motor here, finally. Took off one of the exhaust manifolds. Has square port heads. Do I need square port headers or can I use these B-body round ports?

Overhang meaning the header flange will hang over the ports a little, for racing purposes or higher performance demand it would cause turbulence, but for a street driven car with a mild build you wouldn't even know the difference.
